In the article, research work was carried out to determine the chemical composition, physical properties, and commercial characteristics of NPCa fertilizer obtained by direct neutralization of acidic pulp obtained by decomposing Central Kyzylkum washed calcined phosphate concentrate (LCPC) in the presence of nitric and sulfuric acids in various ratios. X-ray studies were conducted to determine the salt content of granulated NPCa fertilizer.
